Description

Technical Field

[0001] The utility model relates to the technical field of transmission line wiring construction devices, in particular to a traction rope damage inspection automatic stop device. Background Art

[0002] In the construction of power transmission line stringing, anti-twist wire rope is one of the main construction tools, mainly used for pulling conductors and traction ropes. At present, the objects that power transmission lines need to cross are becoming more and more complex. The main crossing objects are high-speed railways, subways, power lines, highways, roads and waterways. Therefore, the anti-twist wire rope needs to pass through all the crossing objects. Once the anti-twist wire rope is damaged or accidentally, it may endanger important crossing objects, so the safety performance requirements of the anti-twist wire rope are very high. In order to ensure the safety performance of the anti-twist wire rope, the anti-twist wire rope must be fully inspected once for each project. At present, the detection of anti-twist wire rope mainly relies on the touch and sight of personnel. When the traction machine pulls the anti-twist wire rope, the inspection personnel wear wear-resistant leather gloves and gently hold the anti-twist wire rope. Through hand touch and close observation, check whether the anti-twist wire rope has broken wires and other problems. However, the above-mentioned manual detection method has low safety. Although wearing wear-resistant gloves, the hands of the inspectors are often stabbed, and the efficiency of manual detection can no longer meet the construction needs on site. Utility Model Content

[0003] The utility model aims to provide a traction rope damage inspection automatic stop device, which can realize automatic inspection of anti-twist steel wire rope, improve efficiency, ensure inspection quality and construction personnel safety.

[0004] To achieve the above-mentioned purpose, the utility model is implemented with the following technical scheme: a self-stop device for checking the damage of a traction rope, which comprises two detection frames, a traction rope, two detection rods, a detection ring, a detection object, an intermediate relay, a power supply control normally closed switch, a micro switch, a power supply and two sliding blocks; the two detection frames are arranged in parallel and vertically spaced apart, the two detection rods are installed in parallel in the middle of the detection frames, the traction rope is arranged between the upper and lower detection rods and passes through the two detection frames, the two sliding blocks are slidably installed on the detection rods and can slide along the length direction of the detection rods, the detection ring is passed on the traction rope, and its upper and lower ends are respectively connected to the upper and lower sliding blocks through connecting rods, and the detection object is installed in the detection ring and contacts with the surface of the traction rope.

[0005] The micro switch is connected to the sliding block, and is also electrically connected in series with the intermediate relay and the power supply; the intermediate relay is connected to the power supply control normally closed switch.

[0006] Preferably, the detection object is cotton wool or sponge.

[0007] Preferably, the intermediate relay is an octagonal intermediate relay.

[0008] Preferably, the power supply is a 12V power supply.

[0009] The working principle is: the traction rope slides, and when a worn position appears, the worn position collides with the detection object in the detection ring, causing the sliding block to move. The microswitch automatically closes after detecting it, and the power is cut off. Under the action of the intermediate relay and the power control normally closed switch, the entire traction rope stops running for detection and repair. After completion, the power is started, and this is repeated.

[0010] Compared with the prior art, the beneficial effect of the utility model is that it realizes automatic detection of the anti-twist wire rope without manual detection, so the detection efficiency is high and the detection is safe. BRIEF DESCRIPTION OF THE DRAWINGS
